Cavalary: for environmental reasons
AlexTerranova: &
Cavalary: lower consumption also tends to mean lower temperatures with lower fan speeds and possibly even more reliability
AlexTerranova: I agree with both statements. For me TDP is one of the key decision factors as well.
That's why I suggested Radeon RX 9070 ( 220 W TDP ) over 9070 XT ( 304 W TDP ) actually. ;)
I just can say, for me, those cards are almost equal priced in many cases with so few "difference" that it is barely worth it going for the non XT if i could get 10% more performance for nearly the same price.
The advantage of the non XT obviously is the higher efficiency which is about 25% more efficient in average. Although if we look at the specs and how the XT is achieving the higher performance, then it is clear that It got about 10% more shading units. Yet this alone is not sufficient for pulling 10% away so the clock has been increased as well by about 20% and in order to make this clock always stable the Volt almost certainly has been increased too, in the end leading to 25% more power consumption.
This does not mean the card can not become adjusted to personal needs and if a good piece is gotten by using some adjustment, it may probably be able to run a few % faster with close to the same efficiency. In the end there is more custom possible using this card.
If someone just want a efficient card "out of the box" then certainly the non XT is "easier to deal with", at close to the same price in many cases.
Whats even more important apart from the correct settings is that a capable cooler has been installed... there might be some difference dependable on manufacturer. So, higher power consumption does not always mean "hotter hardware" because the factor cooling is another factor. Lower end cards in many cases do not have the same cooling solution, it depends on manufacturer.
